ISS Daily Summary Report – 9/29/2017

EVA Mobility Unit (EMU) On-Orbit Fitcheck Verification:  Today the crew completed pressurized fitchecks on EMU 3003 and 3008 in order to assess fit and feel of the suits prior to the upcoming series of Octobers EVAs. After the initial fitchecks were completed, the resizing of necessary components was successfully accomplished to ensure proper range of motion during the EVAs. The goals of the upcoming EVAs include: Remove and Replace (R&R) of a Space Station Remote Manipulator System (SSRMS) Latching End Effector (LEE), lubrication of the two LEEs, and R&R of two external cameras.

Three Spacewalks Ahead for Expedition 53 Crew By Ben Evans

Quote
During all three EVAs, Bresnik—designated EV1, with red stripes on the legs of his suit for identification—will wear EMU No. 3003. Meanwhile, Vande Hei will wear EMU No. 3008 for the first two spacewalks and Acaba will wear it for the third.

Yes, as per Rob Navias, earlier today:

Bresnik will wear EMU #3003 for all three EVAs
Vande Hei will wear EMU #3008 for first two EVAs, Acaba will wear it for the third EVA

Best quote heard during an inspection, "I was unaware that I was the only one who was aware."

I believe there are four LEEs on orbit: LEE A and B on the SSRMS launched 2001,  POA LEE on the MBS launched 2002, and spare LEE on ELC-1 launched 2009. The plan is to swap LEE A for POA LEE now, and LEE B for spare LEE in 2018;
LEE A will remain on POA for now but be returned to Earth for refurb and reflight at some point.

Do I have this right?
Is there an operational need to have a LEE on POA or just a nice to have? They do use it for temp
stow now and again.

Yes, Providing power and data to the HTV pallet (Ie pallet heaters for batteries et cetera) and can also be used to grapple an experiment and would be used for Radiator R&R or solar array wing R&R ( SAW R&R is currently not planned at this time. It would require a specialized carrier for launch and berthing) et cetera.
Space available CSA would also like to see LEE-B returned. Extensive ground testing and analysis prior to LEE-A teardown for refurbishment is planned and would likely see the LEE Ground Spare be launched to allow LEE-B return. If the station is extended to 2028 as is currently in work discussions wise then we could see LEE-A launching to become the new on orbit spare on the pallet and LEE-B would serve as the refurbished ground spare.
